2017 California/Southwest Weather Thread

[Reg]

It continues....1.85" and still rising.

[Guest happ]

1.65 here today. Well over 2" in San Gabriel valley/ Orange county. Long Beach 3.87. Lots of interesting footage of event. 

 

54/ 48

[Bonk]

2.53" here in Modjeska and it's still coming down.

[Anti Marine Layer]

2.72" for Fullerton Airport, but San Diego has just had a few tenths of a inch.

[Anti Marine Layer]

As much as I'm excited by the 2.72" we got in Fullerton, I'm extremely disappointed by how this storm ditched San Diego. Only 0.18" with the rain already moving out.

[Reg]

2.11", slowing down a little bit now, but still going.

[Guest happ]

0.54 overnight

8.57 - month

15.13 - year [jul-jun]

 

Also observed graupel during a brief heavy shower this morning

[Anti Marine Layer]

So far Lindbergh Field has a total of 0.5" from this storm, compared to 2 to 3 inches for most of Orange County.

It was an interesting morning today.  I got awakened to a tornado warning for Santa Barbara county on my phone this morning.  Although I was not near the warning area there was a brief period with heavy pea size hail around 6:45 am.  There was still some hail persisting, unmelted in one of my plants located in a shaded area, this afternoon around 4:30 pm.  

 

January rainfall total around 9" and Season total at 14".

 

There is finally some runoff into the Gibraltar and Cachuma reservoirs in Santa Barbara county.  

[Anti Marine Layer]

We had one loud bang of thunder last night and an intense downpour that lasted for a few minutes around 4:45 AM. The rest of the day had some occasional showers, but no more thunder. Right now it has mostly cleared out.

 

Still hoping for San Diego to get some more showers tonight and tomorrow.

Having hail stay around for most of the day is a real treat. I recall the same phenomena several years ago. Frost is very likely for the next few nights. Many areas are in the 30's this morning especially inland valleys. Coldest minimum this month/ season here.

Hoping for another wet period that could occur early next month. Coldest mean for the month today.

 

58/ 40

[Anti Marine Layer]

It's a beautiful morning with sunrise finally a few seconds earlier than on Winter Solstice. We have gained 29 minutes of daylight in the afternoon. After February 11, however, sunrise will be changing at a faster rate than the sunset.

 

Lots of snow on the San Bernardino mountains, but in Lake Forest, they are mostly blocked by the Santa Ana Mountains.

[Guest happ]

January has been cooler than normal thanks to clouds/ abundant rainfall. Remarkable snowfall in southern Sierra really helps.

Back to boring weather for a while. Since the atmospheric river that gave Orange County and LA County so much rain with the last storm mostly bypassed San Diego, we will need to hope for some storms focused on San Diego County.

[Guest happ]

Nice to see recovery of rain deficits but southern most Santa Barbara and much of Ventura county are still in extreme drought. Overall a wonderful improvement for California. Some very cold morning temps but not even close to records; frost wasn't as widespread as predicted.

 

Wednesday: 61/ 43

Eh based of Happs map I would say Ventura/SB need it more still.

[Dylan]

We still can really use more rain in Santa Barbara County.  Our main reservoir, Cachuma is still under 15% capacity. 

[Dan the Weatherman]

3.70" fell here in Orange with this last storm, bringing my season total so far to 16.34". It is nice that we are having a break from the storms for a little while, but I hope we see more storms sometime in February, and hopefully the on and off wet pattern will continue into the spring! If the wetness continues, then further reductions in the drought are likely.

There has been a bit of discussion, as you know on WW, concerning the corridor of deepest moisture during last week's rainfall. Orange/ LA counties benefitted nicely. Later next week another storm should provide more rain/ snow primarily in NorCal.

The northwest corner of LA county is also in extreme drought. Basically Mojave desert, that area can make up winter rain deficits in a single summer thunderstorm.

[Anti Marine Layer]

Very windy today. It made a big mess in my backyard. Good thing the hills are still moistured from the recent storms.

[Dan the Weatherman]

Barometric pressure readings have been very high in CA today with strong surface ridging. Readings were in the 30.40s and 30.50s in many areas. There were readings as high as the 30.70s and 30.80s in NV, ID, and eastern WA as well, closer to the high's center. This is the same high that is helping to fuel our strong Santa Ana wind event.

[Guest happ]

Wind hasn't been particularly strong here compared to parts of the San Fernando valley/ IE and Orange county. The San Gabriel mts often block/ greatly modify santa ana winds depending on the location of high pressure.

 

Friday: 64/ 46   

[Anti Marine Layer]

It is quite warm today after the cool, windy day we had yesterday.

[Guest happ]

Boring weather for a while. Model indecision re: rain this week.

 

Saturday: 74/ 50

Some past Februaries have been very wet. Rooting for the same this year.

 

Rain data for my location:

 

1992: 11.49 [followed by 8.71 in March]

1998: 16.28 [remarkable : 35” rain year]

2000: 8.03

2001: 8.47

2004: 8.26

2005: 14.92 [rain year over 50”

2009: 6.40

[Anti Marine Layer]

From 42 to 73 and still going up. It's a beautiful day out there.

Must be hard to enjoy though thinking about how badly San Diego got screwed last week...

Nope, I am still enjoying it a lot. It reached 82 here at UCI, where I took my dog for a walk to hunt squirrels.

 

Picture coming later. Android has a new bug where it will not attach files from my phone.

Here is the picture

Is one of those peaks Mt Baldy?

 

First 80° since Dec 29; hardly any days above 70 this month.

[Dylan]

Low around 33 in morning to high around 76 this afternoon.

[Dan the Weatherman]

Here are the February rainfall totals for downtown Los Angeles since 2012:

 

2012: 0.16"
2013: 0.20"
2014: 3.58" - 3.29" fell on last 2 days of month.
2015: 0.83"
2016: 0.79"

 

This has been one pathetic streak for a month that historically has been one of the wettest for the region. I think we managed 3.58" in February 2014 just by sheer luck on a one and done event that led to more dryness afterward, and had that rain fallen just a couple of days later, February 2014 would have only received 0.29".

[Dan the Weatherman]

First 80° since Dec 29; hardy any days above 70 this month.

 

80/ 58

 

Yep. Mt Baldy is above the two tall palm trees.

[Guest happ]

Good amount of moisture from mid week into Superbowl weekend per European model but all of it in NorCal.

[Guest happ]

I'm liking the model trends for rain even into SoCal later this week/ early next week.

 

Monday: 80/ 60
